March 2013 doc.: IEEE 802.11-13/0057r1 March 2013 Abstract Thoughts about Design Options for the TGaq meeting in March 2013, Orlando, Florida, USA Stephen McCann, RIM Stephen McCann, RIM

Need for Project (From PAR) March 2013 doc.: IEEE 802.11-13/0057r1 March 2013 Need for Project (From PAR) This amendment will provide mechanisms that assist in pre-association discovery of services by addressing the means to advertise their existence and enable delivery of information that describes them. This information about services is to be made available prior to association by stations operating on IEEE 802.11 wireless networks. There are existing higher layer service discovery/description approaches (e.g. UPnP, Bonjour) as well as mechanisms to deliver information in pre-association states (e.g. just as ANQP can be delivered over GAS).

Way Forward What do we want to do? Use Case/Requirements analysis March 2013 doc.: IEEE 802.11-13/0057r1 March 2013 Way Forward What do we want to do? Use Case/Requirements analysis Call for proposed solutions (complete/partial) Down selection criteria (if multiple proposals) Simple Protocol (quick) Communication plan with other Fora (e.g. Wi-Fi Alliance?)

Quick Option TGaq develops simple MAC protocol March 2013 doc.: IEEE 802.11-13/0057r1 March 2013 Quick Option TGaq develops simple MAC protocol Meets low level requirements of use cases Other Fora deal with higher layers (L2+) Liaison to other fora of our use cases Stephen McCann, RIM Michael Montemurro, RIM

GAS GAS designed to provide pre-association protocol March 2013 doc.: IEEE 802.11-13/0057r1 March 2013 GAS GAS designed to provide pre-association protocol Request/Response mechanism to network server Asynchronous timing Built in server side delay (comeback delay) Timing can be altered to reduce amount of Request/Responses Stephen McCann, RIM Michael Montemurro, RIM

ANQP Access Network Query Protocol March 2013 doc.: IEEE 802.11-13/0057r1 March 2013 ANQP Access Network Query Protocol Designed to fetch static access network data from AP Request sends integer cook book value (e.g. 258) Response returns data (e.g. Venue Name) RLQP similar for TVWS registered location data Other QPs can be easily added New “ANQP” protocol to carry UPnP, Bonjour frames Do we have to determine which frames would be required? Adjust the timing/frequency of queries Stephen McCann, RIM Michael Montemurro, RIM

Protocol Ideas Some simple new service discovery messages March 2013 doc.: IEEE 802.11-13/0057r1 March 2013 Protocol Ideas Some simple new service discovery messages Upper layer encapsulation Return Codes Signed (secure) messages? Stephen McCann, RIM Michael Montemurro, RIM
